Homework Help: chemistry

Posted by dave on Saturday, February 5, 2011 at 7:00pm.

Consider a red flame color produced by excited lithium with a wavelength of 671 nm. What is the mass equivalent of 1 mol of photons of this wavelength?

I can get as far as Js of E

Can't seem to find equation to turn Js into mols, or photons into mols, for Js into photons.

I'm lost
